Thank you for purchasing the Stereo 40 6AS7. A
great deal of care has been taken in the design,
selection of components and production of this
amplifier. We are sure that you will hear the
difference.
In order to get the best out of your amplifier,
please read the enclosed notes. Even if you are
experienced with hi fi please read the 'quick set
up guide'. Should you be uncertain about
anything to do with your amplifier please contact
us for advice.
Valve (or Tube) amplifiers do the same job as a
solid state amplifier, but they do it differently. And
whilst solid state specifications look good on
paper even quite modest valve amplifiers can
have a richer, more textured sound. Your ears will
have become accustomed to your old amplifier,
sometimes it may take some hours before your
ears attune themselves to the new sound.
Your source, loudspeakers and room acoustics
will also affect the sound before it finally reaches
your ear. Some people find a small adjustment in
re positioning their speakers can help too. The

weakest link will always affect the final results
when making judgements. Not all recordings are
'equal'! Therefore an amplifier which faithfully
reproduces the input signal will also reproduce
imperfections in the tonal balance and the
recording itself. Setting up and judgements should
be made with a 'clean' well balanced recording.
What is the ST40 6AS7?
This amplifier is a push-pull pure triode integrated
amplifier, running in class a/b mode, using the
excellent 6AS7 valves in split bias mode. The
driver and phase splitting is all triode. The pre-
amp is a high quality 'Passive' circuit using silver
audio cable and an ALPS 'blue' volume control. It
is sensitive enough to be used with all modern
source equipment having an output of 250mv or
greater. Its simplicity coupled with point to point
hand wiring without the use of printed circuit
boards results in an open euphoric sound that is
wonderfully detailed and warm sounding.
